The dot reports on the new version of Qt, as discussed by Qt developers Simon Hausmann and Andreas Aardal Hanssen. Much optimizations have already gone in the 4.5 development tree, and more is to come. You can also expect many functional improvements to the WebKit webbrowser engine, graphical effects and a new animations API.

"I'm getting the impression you don't know what Webkit is. Apple didn't fork webkit, they forked KHTML which created webkit. Webkit is what Safari is using. Qt 4.4 has an older version of webkit that they spent a while porting, and it has quite a few limitations. The last I heard, 4.5 was going to update it to the latest trunk code available and be much improved.

i admit i dont know much about webkit, my undersstanding they did fork webkit an gave it to the Opensource Devs to Make something from it or out of it "

You have got it the wrong way around. KHTML is the origin of the codebase. Webkit and Safari are based on KHTML, not the other way around.

"On January 7, 2003, Steve Jobs announced that Apple had developed their own web browser based on KHTML rendering engine, called Safari. ... Safari uses Apple's WebKit for rendering web pages and running JavaScript. WebKit consists of WebCore (based on Konqueror's KHTML engine) and JavaScriptCore (based on KDE's JavaScript engine named KJS)."

Apple made some improvements to the original KHTML code and were a bit tardy in giving some of those improvements back to KHTML as they were supposed to. It took a bit of reminding to get Apple to do the right thing.

"In June 2005, after some criticism from KHTML developers over lack of access to change logs, Apple moved the development source code and bug tracking of WebCore and JavaScriptCore to OpenDarwin.org. WebKit itself was also released as open source. The source code for non-renderer aspects of the browser, such as its GUI elements, remains proprietary."
